Canola Seeding Depth and Row Spacing. 1  Canola seeds are small, and careful placement at a relatively shallow depth is required. 2  Best germination and emergence occur at 1/2 to 1 inch under conditions of good soil moisture.  Canola has difficulty emerging from crusted soil.
Serotonin plays a role in many brain processes, including body temperature regulation, sleep, mood, appetite, and pain. Problems with the serotonin pathway are linked to obsessive-compulsive disorder, anxiety disorders, and depression.he Dopamine Pathways. Dopamine is the neurotransmitter used by the reward pathway (also called the mesolimbic pathway, which is closely linked with the mesocortical pathway).
The excess of serotonin leads to a situation called serotonin syndrome, which has symptoms of shivering, diarrhea, muscular rigidity, fever and seizures. The deficiency of serotonin causes anxiety, depression, fatigue, and sleep and appetite disorders. The patients with deficiency of serotonin are treated with drugs like fluoxetine to block the elimination of serotonin from the synaptic cleft. These drugs are called selective serotonin reuptakes, or SSRIs.
